Treeborn+traps is risky, especially Solemn Warning, because you can't get rid of the in any timely fashion without borking your lifepoints.

I'm also not feeling the tripple Poseidra. It can be summoned from the hand or the graveyard, so 3 is going to clog your hand, because you don't want to summon from the hand when you can take it from the gy.

Max up on E-cons, can't go wrong with those. Even if it's just the a/d effect. Also, Salvage can be a lifesaver.

Thanks for the tips. Since I didn't give a full explanation (and not sure if you are, but in case you are interested) you never actually use poseidra's effect (I have used it 1-2) because you use slushy to get it, and then lancer to recycle slushys. You run 3 poseidra to get one with swap frog, so that you can discard it for swaps special, and send slushy. Then normal swap eff for slushy. Now you have 2/3 slushy needed, and if you have another water monster can get the third slushy and special poseidra for a 2800 atk monster that can come bcak from grave 2 more times.

However, I would like to play 2, I just don't know if it will consistent enough, since I can't search for it.

So it's primary role is ro make Slushy needed? I thought you were going to bring it out with 3 Frogs, which wouldn't be very good. Now I know, and trust me when I say I'm interested, I see two ways to fix it.

So now you're at the crossroads: Either drop Slushy and Poseidra to go full-on hardcore LancerFrogs, or make Poseidra searchable at 2.

And that's where I'm going to stop typing, because I'm on my phone. And typing the wall of text that is currently going through my head, is not really feasable on a mobile device. Consider this a teaser until I hit my computer...

Full LancerFrogs will probably mean getting rid of Poseidra and Slushy. It'll make the deck less original, but it's a tried and tested deck that's not overused. Mind you, it's not uncommon, but it's not cookiecutter T1 deckstealing.

It'll entail removing some cards to make room for changes.

First off, the traps have to go. They only clog up the backrow, messing up Treeborn-plays. All 4 traps are out, because they're traps that need to be played correctly, and idealy stay on the field until you can play them in a good way. And when your LP dip below 2000, Solemn Warning becomes a massive showstopper that you'll probably have to destroy yourself.

Secondly, Poseidra and Slushy really have no place in LanceFrogs. Sea Lancer is a Beast Warrior, and cannot be summoned by Slushy. Slushy will be there to SS Poseidra and be reused by Lancer. But ideally, when you get out your Poseidra not once, not twice, but thrice and still are not near a win, you're probably doing it wrong. And with Slushy out, Poseidra becomes a very bad card in the deck.

Your focus is going to be on Sea Lancer, and earlier on making Gachi Gachi Gantetsu and Banishing Frogs. Tourguide makes Rank 3's, which is good, but not really usefull in Lance Frogs. It's completely possible, but really not that great for a sleak Lancer-focused deck. Sangan is an amazing searcher, and Tourguide summons it, but it doesn't get it's effect when detached. It's actually counterproductive to Sangan's roll in the deck. TGU's are out.

The 12 cuts:

2 Solemn Warning

2 Torrential Tribute

2 Tour Guide of the Underworld

3 Slushy

3 Atlantean Dragon Poseidra

This leaves us with 10 spaces to work with for a 40-card deck. It's not the end of the world to run a 41-42 card deck, but when the opportunity arises, I'm not going to pass it up.

You run Treeborn, so you should play Enemy Controller. It's a law somewhere. Because you can SS Treeborn, activate ECon from your hand, tribute Treeborn, grab a monster, then RESUMMON TREEBORN! That's a plus 2, +1 for you -1 to the opponent. I'm going to recommend running the full 3, so adding 2.

Salvage is another big one. Getting back your Frogs, and even your Lancers! It's just that good! You will be banishing a lot of monsters, so running 3 is a bit enthousiastic, but I think 2 is the bare minimum. Add 1.

You're going to burn through Gachi's like crazy, and you will want those back. You can also never go wrong with more Caii. Pot of Avarice gives you those cards back, on top of being an extra draw. It's limited, so add 1.

Poison Draw Frog is really good. REALLY GOOD. If you can slap 2 on your Lancer, your opponent will dread destroying it. You'll simply draw cards. Dupe searches, and is really good, but you can't deny a good draw. I think adding one more will make it appear more often. Adding 1.

You have 2 Caii right now, and 1 LaDD. They're great cards that you can use to solve problems, stall or, in LaDD's case, stop the opponent dead in their tracks. Maxing Caius is great, and you could even max LaDD. That's 1 Caius and 2 LaDD's, adding 3.

Now we're still two cards short. There's some different ways to fill it up, and I recommend you pick what you like and, not unimportant, what you have access to.

One is to add The God Of Destruction, Obelisk the Torme-ntor. He's a viable card in Frogs, forcing action and winning games. Like Caius and LaDD, he's another out, another card up your sleeve. You could add 1 or 2, but I recommend 1.

The second is to add another Battle Fader. He's great OTK-protection that also serves as Tributefodder for Lancer, Caius or even ECon in a pinch. Maxing out is a viable option.

Thirdly, you could add 2 Tragoedia. It's an amazing card that you can drop as OTK-protection, then use as a beatstick, steal an opponent's monster, or change it's level and XYZ into something good. It's sheer versatility makes it a good card to add. 2 is great, 1 is viable.

Fourthly, Moulinglacia, the Elemental Lord. It's expensive, but it's just a great way to add to the war of attrition that LancerFrogs like so much. Spending all their destruction on Lancer, only to drop 2 more cards to Moulinglacia. It's really, really good and deserves mention.

And finally, Treacherous Traphole is a great trapcard for a deck that doesn't really use them. It's a little risky, but completely viable. Just set it as late as possible, or as early as possible, depending on the matchup.

Take your pick, mix, match, experiment and customize. It's up to you here.

Slushy/Poseidra build:

Slushy decks are a completely different barrel of fish, no pun intended. And as such, will be built completely different. A bigger focus on Slushy will make the deck more consistent, but I will try to keep Sea Lancer in it.

The cuts will be the traps once again. 4 traps, gone.

Soul Taker is an amazing card, but there's no space for it right now. It's out for spaceous reasons.

Poseidra at three will clog like madness. You say you can't search it, but that's not true. It has to be in the graveyard, which is not exactly hard to do. I'm willing to try 2 Poseidra's.

LaDD is a great card, but like Soul Taker, you have so many great cards, some are just not going to make the cut. It's out for a bigger focus on Slushy.

With the bigger focus on Slushy, tributesummoning takes the backseat here. Soul Exchange is out.

The 8 cuts:

2 Solemn Warning

2 Torrential Tribute

1 Poseidra

1 Soultaker

1 Soul Exchange

1 Light and Darkness Dragon

That's 8 cards out, leaving only 6 spaces to add cards to.

The Big One is Foolish Burial. Get that Poseidra in the GY, get that Treeborn in the GY, get any Frog of your choice to the GY. It's an amazing shadow-plus, meaning it's a -1, until you do something with that -1. Send Poseidra to the GY (-1), then plonk it on the field with Slushy (+1) to break even.

The other 5 spaces are, once again, personal preference and availability.

One option is to do a Genex-engine: 3 Genex Undine and 2 Genex controller, or 2 of each, your choice. Undine is like a Foolish Burial, but it also plusses by getting you a free tuner. Free. For no reason! It's just that good.

A second option is to go more safe and add 1 Salvage. Like in the LancerFrogs, it gets everything you could ever want back to your hand.

Third option is a 3rd Caius. Only requiring 1 Tribute, it's a 1-time out to a problem card, that walks like a 2400 beatstick.

Burial from a Different Dimension: you don't always have Lancer available, but really need to reuse some Slushy or Frogs. Burial gets that instantly. Another Shadow-plus.

Adding another Poison Draw Frog is another way to add consistency. Getting those draws every time the opponent tries to get rid of Lancer, it makes a war of attrition a war of crazy plusses!

And finally, Moulinglacia. It's expensive, but it's so good. Like in Lancers, it's a walking, talking Delinquent Duo.

Final Word:

There's always other options, and don't stop looking. Try some stuff, and decide what you like. Lancer is an amazing card that does something a lot of other cards can't, namely wasting the opponent's resources. Decks like Wind-Ups try their best to prevent disadvantageous play and hope to win in 1 turn. Lancer laughs at that and enjoys the long, drawn out games. Using card after card that cannot be destroyed: Lancer himself, Gachi, LaDD or just dropping Poseidra turn after turn after turn. It can, and has, topped let and right, so don't be intimidated. Lancer is here to stay.

Wow, thank you soooo much for this! Really interesting ideas that I am really going to try out. I used to run pure lancer before slushy came out...but now...SLUSHY! have to use it, even just to see people's expressions when it comes out xD.

I am currently looking for moulinglacia, but not going great, but i managed to get the big eye and daigustos, so theres hope!

Ya, for my current build, I always hope to get a poseidra, but if not will set up lancer until I do. Also helps when poseidra gets bottomlessed, or when I use up the slushys. It actually goes fast since the 1/3 is just to first get him on the field, then there are all the traps and effects so he can really only reborn twice, that's where the lancer helps. Also, lancer can equip poseidra to help if it gets bottomlessed or d. prisoned.

Again, thank you, unfortunately i wont be able to get everything tested and set up for my locals special new years turny tomorrow, but hopefully for the next one!

Edit: for the fooliosh burial, I used to run 1 when i only ran 2 poseidra. What would you suggest the foolish/poseidra ratio be?

Hey, great you liked what I did. I love LancerFrogs and have dawdled with Slushy for a bit, so marrying the two was fun.

Now to the questions:

Foolish is limited by the Limited/Forbidden-list, so that's always going to be 1 in the deck. Poseidra at 1 would be a little unwieldy. You'd either have to foolish it, an if it's banished you'll have to wait for it to return through Lancer. If you have 3 Poseidra, it can turn into a dead draw too many times. And it's not like your opponent is going to banish all three without you getting one back somehow. That's why I think the sweet spot is 2 Poseidra's; not so many that it becomes a dead draw, but also one spare, just in case something happens to the first.

The Genex Controller conundrum. Genex Controller is a lvl 3 tuner. Frogs are all 2(Allthough Ronin can't synchro), so a lvl 5 is a given. TG Hyper Librarian and Catastor are the best lvl 5's out there, but Hyper Librarion may not even be worth it, due to the low amount of Synchro's you'll be making. If you can find the space, both is nice, but I feel you'll make Catastor more often. Sea Lancer is Lvl 5, making 8 with Controller. It's not amazing, and will be very uncommon, but you could add a Stardust. Caius, being a lvl 6 Dark, can make R-Genex Locomotion with Controller, which is one of the best cards in the game, ever: when it's Synchro Summoned, you can take control of the highest level(level, not rank) monster your opponent controls. No questions asked, for you to keep and use how you see fit. If only it wasn't so annoying to summon and Xyz being big. I have a man-crush on it, but it's probably not something you'll go for a lot, generally requiring both Caius and Controller to be Normal Summoned. Finally, lvl 6. Oh, where are the days when you could yell "Goyo and Brio" and be done... These days, Gaia Knight the Force of Earth and Flamvell Uruquizas fight for the lvl 6 spot. Pick one, direct power in Gaia or potential infinity attack and Piercing in Uru. But because you run Controller an a lvl 3 Water monster, you could add Genex Ally Triarm. It gets effects related to the attribute of the non-tuner: Discard one card to; Wind: opponent sends one card from the hand(Dark World will not trigger, it's send), Dark: destroy a face up Light monster the opponent controls and draw a card(Utopia, Agents), Water destroy a spell or trap card your opponent controls. It's unwieldy, but very good. It also accumulates, meaning Swap Frog and Battle Fader lead to Triarm with the effects of both Dark and Water. It's another option, oft overlooked for Gaia/Uru because of the tuner-requirement: you can't summon it with Veiler.

Lvl 7 and 9's other than Locomotion are probably not worth it. It'll be rare, and you need the space in the extra deck. See what you can get, fit in, and actually use. Assuming you don't throw your deck away after each tournament, it'll give you some stuff to test and try for the next tourny.

Thanks, I will make a list of these and see what I can get today. I started back yugioh in the summer using an obelisk deck with frog engine and started more and more making it pure frog, then lancer, now slushy. It's the only real deck I have and when I try another deck, I don't know how to play without going to my grave for my monsters xD

Any reason for taking out all the traps?
(Please don't say treeborn...since most of the time it is banished for ronin for lancer, or wont conflict/be needed with those traps stopping opponent from summoning, also only use 2 caius and have faders and ronin for that)
